§ The result
UKG leads Aon Assessment on 6 of the 7 criteria.
UKG scores 44 and Aon Assessment 35 under rubric v1.0, a 9-point gap across the ATS-integrated and Assessment cohorts. UKG leads 6 of the 7 criteria and the remaining criterion is level, so Aon Assessment is ahead on none of them; the closest of the 6 UKG leads is Human Oversight Design, Aon Assessment 45 to UKG 52. Data Governance Disclosure is the widest raw gap and the heaviest weighted swing at once (Aon Assessment 38, UKG 56, 15% weight), but it accounts for only 31% of the weighted advantage UKG holds across the 6 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to -8.8 — the difference between the two totals before either is rounded. Shares are of 8.8 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -9 beside that -8.8.

§ Evidence
Cited sources and documented absences, criterion by criterion.
An absence is a finding, not a blank: the reviewer looked for a named artefact and recorded that it is not located. Where a source sits is a fact about hosting only.
